v Application led Uctober 4, 1913. SerialNo. 793,287.

Be it known that l, J ULIUS MISKEY, a subject of the King of Hungary,residing at ton, in the county of Montgomery and Staate of Ohio, haveinvented certain new and useful lmprovements in Pneumatic- Tire Wheels;,and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to maire and" use the same, reference beinghad to the accompanying drawings, and to the letters and figuresofreference marked thereon, which form a part of this specification.

My invention relates .tod new and useful im. rovements in pneumatic-tirewheels.

e .object `of the invention is to provide a wheel of the above characterin which the inflatable tire is so arranged and protected as to avoidthe possibility of punctures taking place therein. f

Preceding a detail description of the invention, reference is made tothe accompany in drawings of which- Trigure 1 is a sectional elevationof a portion of the wheel tread and adjacent ends of spokes; Fig. 2 is across-sectional view on the vline c--a of Fig. l; Fig. 3 isa sectionalview on ,the line b-b of Fig. 1.

Ln a detail'description of the invention, similar reference charactersindicate corresponding parts throughout said description and the annexeddrawings.

1designates the felloe and 2 the spokes united thereto which are commonfeatures of wheel structure and are not requiredto be changed in .anymaterial sense in applying my improvement thereto.

.3 designates a metallic rim having up turned and downturned marginalflanges l and 5. This rim is suitably secured tothe felloe 1. Againstthe downturned marginal flanges 5 an annular plate 6 is secured by asuitable number of bolts 7. This annular plate 6 and theoppositemarginal flange 4 provide a channel rim around the wheel' Mounted oneach side a ainst'thefelloe. iange 4 andV plate 6 is a metalic wall 8which provides an annular inclosed space for the reception of aninflatable casing 10. This inflatable casing ma be made of any suitablematerial having t e proper air-confining'quality as well as tenacity andpliability. In the drawing have shown it to consist of a singlethickness of material. This may be leather and on the interior thereof arubber tube may be placed; the leather or outer :casing 10 serving, inthis case, as a protecting cover. The construction of the inflatablemember does not involve my improvement, therefore, it will be.understood that any suitable inilatableair between the side walls orplates 8-28. These plates 12 constitute the walls of a series ofpl-ungers or air pistons 13 which move be tween said plates against theair confined within the inflatable casing 10. The plates or walls 12project into the space in which said inflatable tire lies a substantialdistance to form`walls for said pistons.V The ends of said plat-.es 12are provided with flanges 9 which snugly join the side walls 8. Being soprojected, said plates 12 engage the upper surface of the inflatablemember 10 and form a seri-es of air ockets 19 in the outer circumferenceof sai member. The pistons 13 engage the outer surface of said iniatablemember above said pockets and meet with a cushion-like resistance as thewheel turns. Each piston consists of two plates secured to three plungerrods 11i which pass downward through openings in transverse guide plates15. The guide plates 15 have downturned marginal flanges 16 whichlapover the outer ends of the side walls 8 and thus maintain said walls8 in a proper position. The guide plates 15 also have lateral marginal flangesl which overlap the outer edges of the piston walls 12 and thusmaintain said walls in a proper position to co-act with the pistons 13.The guide plates 15 are held in position by marginal bands 17 which aremade secure by a suitable number of -screws 18. The space 2 7 betweeneach guide plate 15 and piston 13 may be supplied with a suitablelubricant in assembling the parts.

Secured to the outer ends of each set of plunger rods 14 is a cross-head20, the outer 'surface of which provides seats for a series of bridgeplates 271 which are secured to said cross-heads by a suitable number ofclips 22. These bridge plates 21 constitute the outermost rim of thewheel. Inclosing the bridge plates 21 is a solid rubber tread or tire 23the margins of which are extended downwardly in the form of shields 24which are secured to the metallic side walls 8 by annular bands 25 whichin turn are secured by a suitable number of screws or bolts 26. By thisVconstruction and arrangement of the tread, a dust-proof character isimparted to the wheel.

It will be seen from the accompanying drawings that the inflatable tireis set in a considerable distance from the tread of the wheel and 'thatthe possibility of puncture is wholly eliminated. It will also beapparent that the well known elasticity inherent in the pneumatic tirewill be imparted to the outer circumference of the wheel through theseries of plungers or pistons 13 each of which acts independently of itsneighbor and all of which, collectively, provide the desired resiliency.

While I have with some minuteness described details, I do not wish to beunderstood as limiting myself to any unessential detail for the reasonthat details'in many structures may be varied more or less withoutaffecting results or the essential operation of an invention. This istrue of the present invention. Theremay be more or less modification orchange made in some of the details. The parts may be lighter than theyappear to be in the drawings and it will be understood that suitablematerial is employed throughout.

IVithout departing from the spirit of my invention which is to, in apractical way,

locate the inflatable tire in such a position as to protect it from thepossibility of puncture, I claim as my invention; (l

l. In a wheel of the type specified, the combination with a felloe, ofannular walls united to said felloe and providing an annular chambertherearound, a series of members projected into the outer annularportion of said' Chamberland providing a series of outer circumferentialpockets therein, an inflatable tube within said chamber and pockets, aseries of pressure members engaging said inflatable tube within saidpockets, and a series of bridge plates connected with said pressuremembers and forming the tread of the wheel, substantially as specified.

2. In a wheel of the type specified, the

combination with a felloe, of annular members united thereto and forminga chamber therearound, a series of division members lying within theouter portion of said chamber throughout the extent thereof andproviding a series of pockets i-n said oute'r portion, an inflatabletube occupying said chamber and pockets, a series of pressure membersengaging the outer surface of said inflatable tube within said pockets,metallic tread members united to said pressure members, and an elastictread united to said metallic tread members,s substantially asspecified. 3. In a wheel" of the type specified, the combination with afelice, of members united thereto and/providing an annular chamberthcrearound, ay series of plates extending intol the outer portion ofsaid chamber throughout the extent thereof and forming a series ofpoclrets,fan inflatable tube within said chamber and pockets, acorresponding series of plungers movable between said plates against thecasing Within said pockets, a series of rods fiXedly connected to saidplungers, a series of crossmcmbers to which the outer ends of said rodsare fixedly connected, and a series of bridge plates spanning the spacesbetween said cross members and `supported thereon, substantially asspecified.

4. In a wheel of the type specified, the combination with the inner rimof a Wheel, and a series of channel members united thereto and formingan annular channel` therearound, of a series of plates projected intothe outer circumference of said channel and providing a series ofpockets therein, a series of plungers movable between said pocket platesand. forming outer closures of said pockets, a compressible tube withinsaid channel and pockets and engaged by said plungers, a series of crossheads fixedly connected to said plungers, an outer inclosing case havingmarginal extensions united to the channel members, and a'series of treadmembers interposed between the cross heads and supporting said outerinelosing case, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
